NITED IMPROVEMENT IN HOLDERS FOR CAR-DOORS.

Specification forming part of Letters Patent No. ll 2,@52, dated April19, 1804.

To all whom it may concern:

Be it known that l, GERMOND CRANDELL, of the city and county ofWashington, in the District of Columbia, have invented a new andimproved mode of holding car and other sliding doors shut and preventingtheir closing when open; and I do hereby declare that the following is afull and exact description thereof, reference being had to theaccompanying drawings and to the letters of refer ence marked thereon.

The nature of my invention consists in using the rollers or wheels uponwhich all sliding doors are moved to hold. thes aid door at anydesirable point without the aid of any other fastening.

To enable others skilled in the art to make and use my invention, 1 willproceed to describe its construction and operation.

A represents the door partly open, standing upon the track at d,supported by the wheels or rollers b b. c c 0 represent sections of thetrack removed or depressed in such a manner as to allow the wheels Z) bwhen the door is entirely closed or entirely open to drop into them, andthereby prevent its opening or closing except by the application offorce, thus obviating the use of other fastenings.

The drawing represents the wheels or rollers at the bottom of the door,but this mode will apply equally well if it is desired to put them atthe top. It also represents the track as raised above the threshold, butshould it be desired to drop it below, forming a groove, the depressionsfor the wheels should be made entirely through to prevent their fillingup. In some cases this may be found necessary, even with the raised trck.

lVhatI claim as my invention, and desire to secure by Letters Patent,is-- The combination of a sliding door supported on wheels or rollers,with an indentation, depression in, or removal of, the track d d at thepoints 0 c c, in which to admit the wheels 0 b to adjust themselves whenthe door is either open or closed, arranged to operate in the manner andfor the purposes herein set forth.
